Why are white dots appearing on my laptop’s screen?
Random glitches on your laptop or PC’s screen can be very annoying. The ‘white dot’ issue is quite common and can arise due to a plethora of reasons. Here are some of them.
- Dead pixels: When a pixel on the screen stops functioning, it sticks out like a sore thumb. It fails to replicate the colours displayed on the screen. A cluster of dead pixels can cause white spots on the display.
- Water-related damage: If your laptop screen was recently exposed to water splashes, it may start to malfunction. Some water droplets can find their way behind the display and damage its hardware.
- Hard impact: If your laptop or PC monitor takes a fall, it can damage the hardware of the screen, resulting in white spots or dead zones.
- Wear and tear: Old devices tend to wear out after years of use. In this case, you will need to replace the worn-out parts or switch to a new device.
Clean the screen
White spots often appear on the screen due to the collection of dust and grime. To prevent this from happening, use a microfibre cloth to clean the display. A microfibre is less likely to scratch the surface and leave minute fibres on the screen. To remove the more stubborn dirt particles, dip the microfibre cloth in isopropyl alcohol before wiping the screen.
Fix the dead pixels
If the dead pixels on your laptop’s display are causing the white dots to pop up on the screen, you can fix them using JScreenFix. But before you do that, run a dead pixel test to make sure that is the case. Use this tool to run the test on your laptop. If you identify any dead pixels, go to this page and click on ‘Launch JScreenFix’. Drag the pixel fixer over the dead pixel and leave it running for 10 minutes to fix it.
Apply pressure on the screen
If the online tool mentioned above did not fix the dead pixels, applying a little pressure on them may help. Make sure your finger or palm is wrapped in a microfiber cloth before applying pressure on the screen. Do not exert a lot of pressure or you may end up damaging the display even further.
Reinstall display drivers
Outdated display drivers can cause malfunctions on the screen. As a blanket measure, uninstall the display drivers even if they are not out of date and then reinstall them. Here’s how.
Step 1: Go to Control Panel and select Device Manager.
Step 2: Click on the arrow next to Display adapters.
Step 3: Right-click on the driver and select Uninstall device.
Step 4: Follow the onscreen instructions.
Once the display drivers have been uninstalled, your PC or laptop will fall back to its native drivers. If you still notice the white spots on the screen, the issue is not being caused by the drivers. You can reinstall the updated drivers and move on to other fixes.
Enter BIOS
If you want to make sure that the white dot issue on your laptop’s screen is arising due to a software glitch, restart your device in BIOS. If you see the white dots on your screen while your laptop is in BIOS, it means the issue is hardware-related. To enter BIOS, restart your laptop and press Delete + F12 while it is booting. This key combination may differ among OEMs, so perform a quick Google search for your laptop model.
